CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 228,358, dated June 1,1880.

` Application led September 26, 1879.

To all whom it may concern Be it known that I, BENSON W. JOHNSON, of thecity and county of Providence, and State of Rhode Island, have inventeda new and useful Improvement in Carpet-Sweepers; and I hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification.

Figure l is a perspective view of my irnproved carpet-sweeper. Fig. 2 isa sectional view, showing the construction of the adjustable handle.Fig. 3 is a sectional view of the carpet-sweeper, showing the roller fordriving the brush, the construction of the dust-pans, the constructionof the cover, and the manner of securing the brush. Fig. 4 is a view ofthe drivin g-roller. Fig.5 is a sectional view, showing the end of thebrush and the driving-roller. Fig. 6 shows a modification of the driving-roller.

Thisinventionhasreferencetoimprovements in the construction of theoarpet-sweeper.

rIhe object of this invention is to simplify the construction andincrease the durability of a carpet-sweeper.

It consists in the details of construction hereinafter specied andclaimed.

In the drawings, A is the box proper, within which the brush revolves.It is made with rounded corners and curved ends, so as to prevent injuryto the furniture.' B is the cover of the box, made of sheet metal andstrengthened by bending the edges b and b and doubling the metal, sothat a strip of leather, cloth, or other iiexible material can besecured at the edgeb andform, when secured to the box, the hinge for thecover. The latch is secured in the same manner at b by being insertedbetween the doubled metal forming the edge of the cover.

The cover is made sti' and rigid by the doubling of the sheet metalalong the sides, while the ends lie closely on the curved ends ofthebox, thus making a tight joint at all points between the cover and thebox, and producing a lighter, more durable, and less costly curved coverthan was heretofore possible.

C C are two dust-pans, made of tin or other sheet metal. To secure adust-tight joint for these dust-pans I extend the ends c of the sheetmetal and nail the bottom to the ends of the box, as shown in Fig. 3.

d is a revolvin gbrush provided with the axles @,one on each end. Theseaxles run in fixed bearings on each end of the box, and to facilitatethe insertion or removal of the brush the cylinder of the brush is madeshorter than the box, the slidef is raised, the axle inserted at thisend rst, and the opposite axle is brought on a line with its bearing.The brush is now moved laterally and the slidef pushed down. The brushis held by the slide f and lateral play prevented.

The ends of the brush-cylinder are provided with rubber or other elasticrings, and under each end of the brush-cylinder a roller, g, alsocovered with rubber, is placed, which rollers g g drive the brush bycontact with the cylinder ol. The bearings of these rollers gg arearranged so that the weight of the apparatus rests on the two rollersand brings them into close frictional contact with the portion of thebrushcylinder covered with rubber. In Figs. .tand 5 the roller g isshown provided with a hole larger than the pin, so that the roll can bepressed against the brush-cylinder. The roller g may be hung in a hingedframe, as is shown in Fig. 6, and the same result obtained.

h is the handle by means of which the carpet-sweeper is operated. Thishandle is secured to the box by means ofthe curved bracket t', providedwith a slot, and the nut h4,the bearing-surface of which ts the innersurface of the bracket L'. rThe handle h is provided with a threadedpin, h3, which screws into the nut.

The improvement consists in a washer, h2, :fitting the curved bracket,and an elastic washer, It', interposed between the end of the handle andthe washer h2. By this arrangement the handle can be more easily turned,and when fastened the handle holds more firmly, as the curved washergives a wider bearing on the bracket than was possible with the endofthe handle.

In Patent No. 194,095, dated August 14, 1877, the handle is adjustablyconfined to a bracket by a nut and without washers. In hoes it is old tosecure the blade at various angles upon the slotted tang of the handle,and to use in these adjustments a plano-convex and a plano-concavewasher, presumably of inelastic material, arranged upon opposite sidesof the curved tang.

IOO

I am not aware that the curved washer h2 and the elastic washer h haveever before been used as herein shown nud described.

Having thus described my invention, I claim as new land desire to secureby Letters Pntent- 1. In ecarpet-sweepe1",tl1e combinntiomwith the box,ofaslieet-metal Cover the sides ofwhieh lare stifened by doubling' thenietzthund which is secured to the box by e liexible materiel securedbetween the bent und doubled edge, substantially as described.

2. A movable handle having a screw end secured by a nut within a slottedbracket, in combination with a curved wash er, h2, bearing I 5 upon seidbracket, mid nn elastic washer, h', interposed between Said Curvedwasher and the end of the handle, whereby the handle may be more easilyturned nud more securely fastened in place, owing to the enlargedbenringzo snr-thee, substantially as shown.
